MATLAB: How to modify the options file for a Network license for multiple releases when asset_info is the same

MATLAB

Some users of our Network license are getting error -25 when they start MATLAB. This began when we update to the R2010b multi release license file. I would like to know how to use all my keys for current and prior versions.

A scenario where this may occur is if Software Maintenance Service was not renewed for some seats of a product. Before you make these changes, you will need to modify the "asset_info" tag in the license file as well. Add the release at the end of the "asset info" tag in the license file. For this example there are 5 seats of MATLAB for R2017a and 2 for R2016b. Modify your options file with the following:

GROUP ml_users_R2017a user1 user2 user3 user4 user5

GROUP ml_users_R2016b user1 user2

INCLUDE MATLAB:Asset_info=999999_R2017a GROUP ml_users_R2017a

INCLUDE MATLAB:Asset_info=999999_R2016b GROUP ml_users_R2016b

Afterwards, you must stop and restart your license manager for these changes to take effect.

MATLAB: How to configure an options file with multiple licenses

Serving multiple licenses from the same license server typically requires you to define an options file to ensure that the correct users receive the appropriate licenses when using MATLAB.

Network license files contain an asset_info tag which is used to identify an INCREMENT line belonging to a specific license by the license number. asset_info tags are consistent between releases and therefore you do not need to update your options file when updating your license file to a new release of MATLAB.

For example, lets say you have two licenses, 111222 and 999888. This configuration would allow the users of license 111222 to access 111222 and prevent them from accessing 999888. The license file would look like this:

SERVER MyLicenseManager 001122334455 27000
DAEMON "C:\Program Files\MATLAB\R2010b\win32\mlm.exe" options="C:\Program Files\MATLAB\R2010b\win32\MLM.opt"
#------BEGIN----------
# License No: 111222    HostID:001122334455
INCREMENT MATLAB MLM 17 01-jan-0000 11 8DE646541AFDDFE9416 \
HOSTID=ID=111222 USER_BASED DUP_GROUP=U asset_info=111222 SN=111222
INCREMENT SIMULINK MLM 17 01-jan-0000 11 2D66AD832109E0698 \
HOSTID=ID=111222 USER_BASED DUP_GROUP=U asset_info=111222 SN=111222
#-------END-----------
#-------BEGIN---------
# License No: 999888    HostID:001122334455
INCREMENT MATLAB MLM 17 01-jan-0000 7 9D164CBED8D11BCC72 \
HOSTID=ID=999888 USER_BASED DUP_GROUP=U asset_info=999888 SN=999888
#-------END-----------

The corresponding options file would look like this:

# Options file for use with MATLAB
GROUP MATLAB_users user1 user2 ...
GROUP SIMULINK_users user1 user2 ...
#
# Include the GROUP users for license 111222
#
INCLUDE "MATLAB:asset_info=111222" GROUP MATLAB_users
INCLUDE "SIMULINK:asset_info=111222" GROUP SIMULINK_users
#
# Exclude the Group users from license 999888
#
EXCLUDE "MATLAB:asset_info=999888" GROUP MATLAB_users

MATLAB: Are the INCREMENT lines ignored when I have two asset_info tags in the line

The FLEXnet license manager cannot process license codes with more than one set of asset_info tags in a single line. To resolve this issue, you can remove either set of tags and restart the license manager. Once restarted, the license should be in a functional state.
